MULTIPLE-PRESSING MACHINE.

Application filed September 27, 1927. Serial No. 222,369.

This invention relates to pressing ma chines as garment and laundry machlnes, and has for its object a multiple pressing machine having its pressing elements so arranged that the machine can be tended to and operated by a single operator with minimum effort and movement, which machine is particularly simple in construction and arrangement of parts, and highly efficient and durable in use.

The invention consists in the novel features and in the combinations and constructions hereinafter set forth and claimed,

In describing this invention, reference is had to the accompanying drawings in wh ch like characters designate corresponding parts in all the views.

Figures 1 and 2 are, respectively, a plan view and a side elevation of a pressing machine embodying my invention.

Figure 3 is an enlarged fragmentary rear elevation of the frame and contiguous parts.

The pressing machine comprises, generally, a frame, a pair of bucks mounted on the frame and extending forwardly and rear- Wardly thereof and converging rearwardly toward their rear ends providing a working space for the operator between them, heads eomplemental to the bucks and movable to ward and from the same yoke levers carrying the heads and pivoted to the frame 1n the rear of the rear ends of the heads, and means for actuating the oke levers.

The frame may be 0 any suitable size, form or construction and comprises a bench 1 supported by front legs 2, and a single centrally located rear leg 3. I

4: and 5 designate the bucks suitably mounted on the bench 1 by .brackets 6, 7, these bucks being-elongated and extend ng forwardly and rearwardly and converging toward their rear ends providing a working space S between the front ends. The bench is usually overlaid by a table 8 which has its front portion between the bucks cut away at 9 to give greater accessibility to the bucks for manipulating the work thereon, and also to the handles for closing the heads.

10 and 11 are the heads paired with and complemental to the bucks 4 and 5. 12 and 13 are the yoke levers which support the heads 10 and 11 respectively, the yoke levers being pivoted on a pivot pin 15 at the upper end of a standard 16 rising from the frame and forming an upward extension of the rear leg 3', the yokes being pivoted on opposite sides of the upper end of the standard 16. These yokes are pivoted between their ends and the forward arms extend lengthwise of the heads 10 and 11, respectively, and diverge forwardly in accordance with the divergence of the heads. The rear arms of the levers extend substantially parallel rearwardly.

The forward arms are connected to the heads through connections which serve in the nature of universal joints to permit the I heads to rock within limits about a transverse fulcrum andalso about a lengthwise fulcrum to compensate for unevennesses in thickness of the article or garment being pressed and hence, to equalize the pressure.

As here illustrated each yoke lever is provided with a transverse fulcrum 17 acting in the seat or notch formed in a block 18 provided on an intermediate plate 19, the rocking movement being resisted by springs 20 here shown as four in number. These springs are located in front and in rear fulcrum 17 and encircled by pins 21 projecting upwardly from the plate 19 through flanges on the yoke on opposite sides of the median line thereof and thrusting at their lower ends against said flanges, and at the upper ends against abutments as nuts 22 on the pins 21. e

The plate 19 is triangular in general form and has front and rear fulcrums 23 and 24 arranged in the median line of the heads nuts 28 on pins 29 projecting upwardly from the head through the plate.

The mechanism for actuating the yoke levers 12 and 13 which may be of any suitable form, size or construction, are alike in construction and are independent of the other. The actuating mechanism for each yoke as here shown comprises a toggle consisting of links 30, 31 pivoted together at 32, the link 30 being pivoted at 33 to the rear arm of its companion lever 12 or 13 and the link 31 being pivoted at its lower end at 34 to the frameor the rear leg,

The link 31, as here shown, is provided with a forwardly extending arm rigid therewith provided with a pedal plate 36 at its front end, this plate being rigid with the arm 35 but adjustably mounted thereon to change the angle of the pedal plate relative to the arm 33. This feature forms no part of this invention.

The press is closed or heavy pressure applied by applying force to the pedal 36 and the press is opened by a weight 38 and springs 39 connected to the rear arm of the yoke levers l2 and 13 c As seen in Figure 3 the rear leg 3 is in the form of a channel opening rearwardly and provided. with laterally extending webs 40 at its lower end. These webs are provided with openings 41 in which the lower ends of the links 31 extend, and the pivots 34 are supported by these webs, The

springs 39 are also connected at the lower ends to the outer sides of the rear leg above the webs 40, Thus the actuating mechanism or the links 31 thereof are located on opposite sides of the rear leg.

The press is held closed by a latch 42 carried by each lever arm 35 and coacting with a keeper or hook 43 mounted on the frame below each lever 35. The latch 42 is movable, and to open the press, the latch is tripped by means of a trip lever 44. The latch mechanism forms no part of this invention.

In operating presses of this type, the operator first closes down the head by means of a handle associated with the head and applies final pressure by stepping on the pedal 36. 45 and 46 designate the handles for the heads 10 and 11 respectively, these han dles being located side by side between the heads 10, 11 comprising inwardly and forwardly extending arms 47 and 48 which project from the yoke levers 12, 13 into the space between the heads,

Owing to the arrangement of the heads and bucks and the handles, the operator can readily tend to both heads and bucks and operate them with minimum effort and minimum moving around, and hence, the pressing operations are greatly speeded up compared with two machines having heads and bucks extending transversely of the machine frames with their handles on the front sides thereof.
